Barrages and canal falls are considered as a readily available option for hydropower generation as the pre-requisites of water and head are conveniently available on such sites. Most important aspect of such scheme is to set the levels of hydraulic structures so that there is absolutely no disturbance to the irrigation flows which is the basic purpose of the barrage and canal network. At the same time finding the optimum level for the proposed structures so that the maximum hydropower benefits are yielded through the scheme without compromising the safety. Present study intends to investigate the same for Marala Hydropower Project (MHP) proposed on Upper Chenab Canal (UCC) off-shooting from Marala Barrage on River Chenab. In order to define the optimum crest level of the spillway such that there is no negative impact on the discharge passing capacity of the UCC head regulator, two-pronged strategy has been applied
i.e. using computational flow dynamics (CFD) computer software and analytical approach. The results of modelling are first…...

Cfd to Monitor Air Quality

...Spring 2011, Purdue University Calumet, Hammond, IN 46323, USA Using CFD to Study Air Quality in Urban Microenvironments Varun Khare Purdue University Calumet Hammond, IN, USA | Abstract The project is concentrated on the study of the plume height coming out of buildings, such as restaurants and cooling towers around the office buildings, in an urban microenvironment, along with the placement of air intakes and exhausts on buildings which can significantly affect the overall indoor air quality. Earlier studies on the effects of building air intakes have been limited to relatively simple situations, unable to treat the complex envelope of most buildings and building groups. Computational Fluid Dynamics (CFD) is a tool that assists in modeling the airflow and dispersion of pollutants among complex urban geometries on the scale of a section of a building’s exterior up to several city blocks. This tool allows more accurate predictions of impacts over a range of meteorological scenarios and alternative building designs and placements relative to roadways and other pollutant sources. The steps in a CFD application are presented including geometry and mesh creation, simulation of meteorological conditions, handling of pollutant sources, and post-processing visualization. INTRODUCTION Design and placement of a building’s outside air intake is a very important......

Competency Modelling

...Competency modelling: A better approach in contemporary HRM practice? Introduction In the contemporary human resource management (HRM) practice, the process of human resource assessment and selection is shifting from the traditional job-based system of HRM to a newly-established competency approach. According to Dubios’ work (1998), more and more medium-sized and larger organizations are adopting the competency approach to replace the traditional job-oriented method to select and assess their employees in the USA and around the globe. This change happens mainly for the reason that the traditional job-based personnel management systems have shown a tendency to break down when jobs are dissolving under more flexible working conditions and simplification of the bureaucratic hierarchies of the contemporary organizations (Lawler, 1999). Based on the works of Nyboe (2004), in principle there are two distinct approaches to align work and competencies: to start with the work and adjust people and their qualifications to work requirements (job or production approach) or, alternatively, to start with the worker and assign tasks to workers according to their skills (competency or training approach). On one hand, in the job approach, tasks are grouped into individual jobs according to what is regarded a rational division of labor, and workers are recruited and trained to meet the requirements of those tasks. On the other hand, a competency approach has a shift of focus from...

System Dynamic Modelling

...1. Abstract System Dynamic Modelling is an approach to frame and solve complex problems. It is widely used for policy design and analysis. System dynamics analysis is a part of Systems Theory which is used to study the dynamic behaviour of complex systems. The theory is based on acknowledgement of the fact that the inter-relations between the various components of a model, time delays between processes are as important to analyse the behaviour of a model as is the analysis of individual components.  SD models solve the problem of simultaneity (mutual causation) by updating all variables in small time increments with positive and negative feedbacks and time delays structuring the interactions and control. In this paper, we have discussed the basic methodology of the technique, and the modelling process. Then, we have discussed the applications of SDM ranging from conventional ones like project management and science and engineering to exploring the concepts of SDM in Brand management and public health issues. 2. Historical background This technique of solving problems was developed in 1950s by Prof Jay Forrester of Massachusetts Institute of Technology, during his involvement with General Electric. He developed his insights about the foundations of engineering which helped him in the creation of system dynamics. He studied the problem of instability in GE employment. In this he did hand simulations (or calculations) of the stock-flow-feedback structure of the GE plants...

Rock Physics Modelling

...Rock Physics Modelling Rock physics is an essential part of any seismic reservoir characterisation project. The rock physics may be as simple as establishing empirical relationships between rock properties or as complex as poroelastic numerical modelling. The sophistication of the modelling will depend on the objectives and the quality and availability of data. Typical objectives of rock physics modelling studies based on well log data are: 1. Quality control of the measured elastic logs: density, p-sonic and s-sonic. Demanding a consistent and meaningful rock physics model can often indicate anomalous and poor quality measurements in the elastic logs that need correction or mitigation. 2. Quality control of petrophysical interpretation. It has been suggested that empirical relationships are more reasonable to use with well log data as it is hard to establish a consistent numerical rock physics model to explain the information from various wells even though they are drilled close by and in the same formations. However, the root of these problems may lie in inconsistencies in the petrophysical interpretations. Insisting on a consistent rock physics model can often highlight inconsistencies within the petrophysical interpretations. 3. Synthesis of elastic logs where missing or the quality is poor. Once a strong relationship has been established between the petrophysical interpretation (or other well log data) and the elastic properties, prediction...

SPREADSHEET mODELLING Spreadsheet modelling As a future financial analyst my work will be based on analysing data from company’s gathered data spreadsheets. Hence it is crucial for my own career success to understand the importance of spreadsheet modelling and its implementation. As according to (Susan Coles, Jennifer Rowley, 1996) “The decision maker’s judgement must be exercised in the interpretation of the data and the final decision making.” There is no better way of benefiting my future career than developing advanced skills in modelling Excel. As I have learned from few articles I read about this subject, there are many advantages of excelling my skills so as problems I should look out for. Firstly, studying advanced Excel modelling not only helps students to build technological knowledge but “also largely improve their practical analytical skills and abilities.”(Junying, 2010). By studying how to model spreadsheets students get a real chance to see how actual data is analysed by spreadsheet build in models and help them to further their own analytical knowledge and see how it works in real life.

Erosion Modelling

...Erosion Modelling Soil erosion is a significant environmental process that degrades the soil in which we rely on for food, fuel, clean water, carbon storage, and as a substrate for buildings and infrastructure (Quinton 2011). It is the disruption of the soil mantle – the pedosphere, or the underlying rock base – the lithosphere by the action of matter of external geomorphic factors, such as water, snow, ice, air, weathered debris, organisms and man (Zachar 1982). Both abiotic and biotic forms of erosion forms patterns that are typical for a particular area such as climate, relief, nature of the surface, activity of the organism, and activity of man (Zachar 1982). It is the degradation or aggradations of the Earth’s surface by the movement of soil material by wind, rain, overland flow and gravity (ASSIGNMENT). Problems with Erosion The movement of sediment and associated pollutants over the landscape and into water bodies is of increasing concern with respect to pollution control and environmental protection. With the expected change in climate over the coming decades, there is a need to predict how environmental problems associated with sediment are likely to be affected so that appropriate management systems can be put in place (Morgan & Nearing). Erosion can impact the productivity of agricultural, post-mining and native systems and is a sign of land degradation (ASSIGNMENT). Soil erosion acts a mechanism for transferring pollutants to surface waters and reduces...

Dynamic Modelling of Parallel Manipulator

...analysis of the 3-DOF Parallel UPU manipulator. The 3 DOF UPU is a parallel manipulator in which the U and P notations are for universal and prismatic pairs respectively, is a well-known manipulator that provides the platform with three degrees of freedom of pure translation, pure rotation or mixed translation and rotation with respect to the base, according to the relative directions of the revolute pair axes. The pure translational parallel 3-UPU manipulators have received a great lot of attention. Over the years many studies have been reported in the literature on the kinematic analysis, workspace optimization, singularities and joint clearance influence on the platform accuracy of this manipulator. However, the evaluation of the dynamic modelling of the parallel manipulators based on the two most famous methods i.e. Newton- Euler and Lagrange’s method have not been clearly discussed so far. Therefore, this project tries to throw light on this area and covers the Newton Euler Strategy for the calculation of the dynamic model of the 3 DOF UPU Parallel Manipulator. 1. Introduction Over the last few decades the parallel manipulators have attracted the attention of lot of researchers because of their complementary characteristic with serial manipulator. The word 'Parallel’ which is used here is to point out is not in the geometrical sense. Though these links act together, but it is not implied that they are aligned as parallel lines, here parallel means that the position......

Homology Modelling

...prediction namely homology modeling, threading and ab initio prediction (Xong, 2006). Homology modeling (comparative modeling) is a computational protein structure modeling technique used to build three dimensional (3D) models of proteins of unknown structure ( the target) on the basis of a sequence similarity to proteins of known structure (the template). Two conditions must be met to build a useful model, the similarity between the target sequence and template must be detectable and a substantially correct alignment between the target and the template should be calculated. Homology modelling is possible because small changes in protein sequence result in small changes in its 3D structures. The 3D structures of proteins in a family are more conserved than their sequences, therefore if similarity is detectable at sequence level structural similarity is usually assumed (Pala, et al., 2013). Homology modelling is a multistep step sequential process involving the following procedures: Template recognition and initial alignment; alignment correction; backbone generation; loop modeling; side-chain modeling; model optimization and model validation. Template recognition and alignment This involves the selection of all protein structures related to the target sequence and the selection of those to be used as templates. The template selection involves searching the Protein structure databases such as protein data bank (PDB); SCOP; CATH and DALI for homologous proteins with......
